I started using Google Docs to backup documents I prepared on my desktop. I eventually found writing in Google docs more convenient than writing on my own computers. I guess “computers” is the key here. I work from at least three machines daily and it is just so easy to login to one remote location and begin working.
Once I have invested several hours in a project, I begin to worry about backups. I trust Google with my files, but it is reassuring to have a second copy offsite (in this case on my desktop hard drive). Google now lets you zip up to two gigabytes of content and download in a single operation. Select the files (perhaps all of your files) and then the export option (available under more options). The process may take some time, but you can ask Google to notify you when the entire process is done.
I have prepared a simple demo if you need more information.
